CAUTIONS AND WARNINGS
When operating this scale:
 To prevent injury and damage to your scale, please follow the enclosed user instructions
to assemble and operate very carefully.
 Exercise caution when assembling the scale column so as to not pinch the load cell
connector cable.
 For accurate weighing, this scale must be placed on a flat, level and stable surface.
 For accurate weighing, verify before each use the proper operation according to the
procedure described in this manual.
 Operating this scale at voltages and frequencies other than specified can damage the
equipment and will void the warranty.
 Do not transport the scale with any weight on the platform.
 Do not exceed recommended weight limit of 500 lb / 220 kg for this scale.
 Do not use in the presence of flammable or explosive materials.
 For accurate weighing, if the “Lo” indicator activates, replace the batteries or switch to
the optional AC adapter as soon as possible.
 If the scale becomes damaged, it should not be operated until properly serviced.
 When replacing / inserting batteries, be sure to use all new batteries.
 To prevent patient injury, the patient must be attended throughout the entire weighing
event.
 This equipment has been tested and found to comply with the EMC limits for the Medical
Device Directive 93/42/EEC (EN 55011 Class A and EN 60601-1-2). These limits are
designed to provide reasonable protection against harmful interference in a typical
medical installation. The equipment generates, uses and may radiate radio frequency
energy and, if not installed and used in accordance with these instructions, may cause
harmful interference to other devices in the vicinity. However, there is no guarantee that
interference will not occur in a particular installation. If this equipment does cause
harmful interference with other devices, which can be determined by turning the
equipment off and on, the user is encouraged to try to eliminate the interference by one
or more of the following measures:
o Reorient or relocate the receiving device.
o Increase the separation between the equipment.
o Connect the equipment into an outlet on a circuit different from that to which the
other device(s) is connected.
o Consult Customer Service or a field service technician for help.

CAUTIONS AND WARNINGS
When operating this scale with the AC adapter:
 Operate this scale exclusively with the AC adapter provided by Health o meter
Professional. Use of an unspecified adapter will void the warranty, and can pose a
serious safety hazard.
 For use with AC adapter model ADPT31 (Domestic, USA) or ADPT30WA (International,
plug kit)
 Prior to using this scale, inspect the AC adapter cord for cracking / fraying, or for broken
/ bent plug prongs.
 Prior to using this scale, ensure that the AC adapter is plugged into an outlet with the
rated voltage appropriate for operation.
 Ensure that the AC adapter outlet is wired to a circuit breaker or other protected power
source.
 Ensure that the AC adapter and scale do not come in contact with liquids, excessive
temperature, or excessive humidity.
 Unplug the AC adapter, and carefully store both the adapter and adapter cord before
moving the scale.
 If the scale is being connected to another medical device, the power adapter must not be
used. Disconnect the power adapter from the scale and use only the battery power.

SET UP / BATTERIES
Preparing the 500KL Scale for Use / Inserting Batteries
1. Remove the protective plastic film covering the display (the film says “FACTORY
CALIBRATED”).

3. With a Phillips head screwdriver remove the screw from the battery compartment cover
located on the back of the display. Remove the battery cover by pressing downward on the
locking tab.
4. Replace or install 6 new AA batteries. Health o meter
®
Professional recommends using an
alkaline or lithium battery, rated for 130°F (54°C) operation. Do not use zinc-carbon batteries.
5. Re-attach the battery cover to the display assembly.

Note: If the set up procedure fails, refer to the troubleshooting instructions. If the problem is not
corrected, contact Health o meter Professional Scales Customer Service at 1-800-815-6615.
Note: If “Lo” appears on the display, it indicates that the battery power is low. It does NOT
indicate a problem with the weight measurement.
Warning: If the scale will not be used for some time, remove the batteries to avoid a
safety hazard. Disposal of batteries must be performed in accordance with the prevailing
national, regional or local regulations which apply to you.

the movement of the patient on the scale, it may take several seconds for the scale to lock onto
the weight.
Caution: To prevent patient injury, the patient must be attended throughout the entire
weighing event.
5. The weight may be held on the display by pressing the HOLD/RELEASE button. To release,
press the HOLD/RELEASE button again.
6. After the weight measurement has been taken and is recorded, have the patient step off the
scale.
7. Press the ON/OFF button to turn the scale off.
Height Measurement Instructions
WARNINGS: Use caution when sliding height rod up and down. The rod should move
smoothly; do not move the rod in a jerking motion. Fold headpiece down when not in

OPERATING INSTRUCTIONS (CONT)
BMI Function
Body Mass Index (BMI) is a ratio between a person’s weight and height and interpreted as a BMI
score. This BMI score is then used as a tool to categorize a patient as underweight, normal,
overweight, obese or morbidly obese.
Note: The scale will not calculate BMI for a patient that is 24 pounds (12 kg) or less.

2. Press the ON/OFF button to turn the scale on.
3. Wait until the “0.0” LB or “0.0” KG appears on the display.
4.Ask the patient to step on the scale. The scale will begin to display weight information and will
lock on the patient’s weight when the stable weight of the patient is determined. Depending on
the movement of the patient on the scale, it may take several seconds for the scale to lock onto
the weight.
5. After obtaining the patient’s weight on the scale, press the BMI button while the scale is on.
6. The display will show 65” (in LB mode) or 150cm (in KG mode). Use the keypad ▲ and ▼
buttons to enter the patient’s height. To determine the patient’s height, follow the height

Zero Function
Zeroes the scale prior to a weight measurement. The ZERO button is also used in the Tare
function as outlined below.
Tare Function
When using this scale, the weight of an object, such as a cane, can be subtracted from the total
weight in order to determine the weight of the patient alone.
1. With all weight off the scale, press the ON/OFF button to turn on the scale.
2. Wait until the “0.0” LB or “0.0” KG appears on the display.
3. Set the unit (LB or KG).
3. Place the object on the scale. The display will show a value for the object’s weight.
4. Press the ZERO button. The word “TARE” will appear on the display, followed by “0.0” LB or
“0.0” KG.
5. Keep the object on the platform, then ask the patient to step onto the scale as well. The scale
will automatically deduct the weight of the object and only display the patient’s weight.
6. When you remove the item from the platform, “under” will be temporally displayed and then
the display will return to “0.0” LB or KG.
